Droop and Preload questions
I've been working on gettting the ride height and droop set properly on my XXX-S and I had a few questions. I have the droop set at 3 in the front and 5 in the rear. I'm also running 4mm ride height front and rear. I have the short threaded shocks in front and the standard length threaded shocks in the rear and I'm running uncut proline foam tires. I'm also running the 1.0" springs front and rear.

The problem is that I had to run very little spring preload to get the proper ride height. Now when I pick the car up, the shocks do not extend fully to the droop screws. When I extend the suspension fully to the max droop, the spring is not under any preload. There is actually about a 1/8" gap from the top of the spring to the adjuster nut on the shocks. It seems that since the springs can not extend far enough to ever make contact with the droop scres, that the droop setting is meaningless.

If anyone could tell me if this is normal or what I need to do to correct it, it would be appreciated. I am assuming you would still want some amount of spring preload at full droop.

Thanks,
Rob

It is normal for the TC springs have some play when the car is off the ground and the shocks are at full droop. You don't want any spring preload when the shocks are at droop.

I would do the droop with the shocks and swaybars (if you have them) detached. After, put everything back on including wheels and use the collars to adjust ride height. After that check for tweak and adjust that out also using the shock collars.

Thanks again,

Don't remember right now so I'll have to check for you when I get home, but aren't the outer hingepin mounts listed as 0/4 and 2? This affects the kickup that will change the overall caster.

The stock hub cariers are definitely not the 4 degree ones. The 4 degree carriers are clearly marked as such. I haven't checked to see what amount of caster the car has stock, though, so if the goal is to get to 4 degrees of caster, you should check this out before buying anything. Sorry, I don't have the part number handy on the 4 degree carriers!

Stock carriers are 0 degrees.Kickup + kingpin angle=total caster.

Kickup is controlled by the pivot blocks that mount inner pins of front suspension arms to chassis. Two mounts included
0/4degree and a 2 degree.

I found these at Horizon but they are out of stock.
A9747 Graphite 2 degree carriers
A9753 " " 4 degree.

You can get 4 degrees total with stock kit or up to 8 with optional carriers.

Default Asphalt Racers!

Anyone who races on asphalt might be interested in this article in the new R/C Car mag. Brian Kinwald has his setup for low bite asphalt as well as high bite. Def. worth checking out!

I just got the sway bars for my xxxs, and noticed they are the same. They both are rears. Is there any difference between the front and the rears?

Ok I just checked the front carriers. As the others say, they are not 4 degrees. Mine is 0 degrees.

There is a difference in the front and rear sway bars. The rear are a bit wider. Both front and rear come in four diameters that are the same. but the geometry is different.

The 4 degree blocks in the front will give the car turn in off power. This tends to cause a push that is easily cured by running 0 degree of toe in the front or mabye 1/2 degree of toe in. The blocks are good with or with out the one way.

Would it hurt to take and bend them in a little to make them fit. My lhs does not have any more. Thanks BrianC for the help.
